Best type nail gun

[merickovach]

I am working on finishing a basement and I am at the point where I'm going to start putting up walls and partitions. My question is what is likely the best nail gun for me. I am 70 but not of course, new to this--I just have never owned a nail gun. There are battery operated ones and pneumatic. Are the battery operated ones the best (if expense is not an issue), or are they too heavy? Can a framing nailer do both end nailing and toe nailing?

Thanks for the help in this.
